Vastavam web: Airbus Chief Executive Tom Enders said on Wednesday he is worried an escalation in a U.S. trade dispute with other countries could trigger retaliation that could impact air traffic.“Of course we’re worried if this escalates,” Enders told reporters following a visit with employees at a Bombardier (BBDb.TO) plane factory near Montreal. “If there are retaliatory measures this could impact air traffic. We very much hope this is not going to be the case.”
